Abstract

The invention relates to a seal cover, a bearing unit and an axle box device. The sealing cover (3) is used for the bearing unit of an axle box device, The sealing cover (3) is annular, two locking projections (10) being formed on one axial end face of the sealing cover, the two locking projections (10) being spaced apart from each other in the circumferential direction and having the same radialposition; the bearing unit is used for the axle box device and comprises a bearing (1) and the sealing cover (3). The axle box device comprises the bearing unit, and the stop protruding part (10) of the sealing cover (3) of the bearing unit and the stop shifting fork (8) of the component of the axle box device form an anti-rotation mechanism.

Description

technical field [0001] The invention relates to the field of bogies. In particular, the invention relates to an axlebox arrangement, a bearing unit for an axlebox arrangement and a sealing bell for a bearing unit. Background technique [0002] The bogie of a train usually includes components such as frame, wheel set and axle box device. The axle box unit is used to connect the wheel set and the bogie frame. [0003] For example, in patent application document WO 2007 / 065413 A1 a sensor-equipped axlebox arrangement for rail vehicles is disclosed, which comprises a bearing for a rotating shaft, a fixed axlebox body surrounding the bearing and a A sensor assembly for bearing state monitoring, wherein the bearing at least includes an inner ring fixed on the rotating shaft and an outer ring fixed on the shaft box, and a sealing cover is fixed on the outer ring, and the sealing cover is on the axial end side of the bearing Sealed bearings. The sensor assembly of the axle box d...
